Hi, i am using the ADS1291 and want to power him down. I am using Analog 3V3 and Digital 3V3. So i should get 4uW or 1.2uA of power consumption. I put the "PWDN/RESET" PIN low and i still measure between 200 and 300 uA power consomption from it. Do i have to write on his registers to power down and achieve the 1.2uA? Or does it all goes power down when i put the "PWDN/RESET" PIN low? PDB_LOFF_COMP: Lead-off comparator power-down PDB_REFBUF: Reference buffer power-down PD1: Channel 1 power-down
